Embodiment Construction

[0024] The roots of human extracted incisors and premolars were removed by using diamond grinding wheels. The facial surface was then flattened by high abrasion discs (Tycet Ltd, Hemel Hempstead, Herts, UK) until it was flat enough to fit approximately 50:50 4 x 4 mm blocks of enamel and dentin. The lingual portions of the teeth were then cut with a Two Well Model 3242 Wire Cutter (Ebner, LeLocle, Switzerland), leaving slices approximately 2.5 mm thick. The samples were prepared plane-parallel. The surface was then sequentially polished with 3 μm and 1 μm diamond suspensions (Kemet International Ltd, Maidstone, Kent, UK) and a final polish with 0.3 μm Micropolish II (Buehler, Coventry, UK). The samples were then sonicated for 5 minutes, rinsed with Milli Q water (Millipore, UK), and then sonicated again for 5 minutes to remove any smear layer formed during polishing.

[0025] Untreated samples were imaged according to the following method.

[0026] The samples were mounted ...

Abstract

A method of demonstrating the impact of a treatment on a surface comprising the steps of: i optionally imaging at least one untreated surface ii applying at least one treatment to the surface(s)such that if step i) is not performed at least two different surfaces are treated with differing treatments, iii imaging the treated surface(s) to create an image; iv converting the imaging data into a format suitable to create a magnified image on a 3D printer; v producing a 3D model of each of the imaged surface(s).

Description

technical field [0001] The invention relates to a method for demonstrating the effect of a treatment on a surface. Background technique [0002] WO 14041186A1 describes a system or assembly, eg software for 3D modeling of the body. [0003] Consumers are aware of the damage that aging and certain aggressive cosmetic treatments can do to their body surfaces or possessions. Particularly in personal care, although remedial measures are available to mitigate these deleterious effects, the concept can be difficult for consumers to grasp and the full effects of remedial treatments difficult to fully understand. Contents of the invention [0004] The invention relates to a method for demonstrating the effect of a treatment on a surface, the method comprising the steps of: [0005] i. Optionally, imaging at least one untreated surface, [0006] ii. applying at least one treatment to said surface such that if step i) is not carried out, at least two different surfaces are treate...
